TOUCH SENSOR WITH REFINED CORNER, EDGE, AND OTHER STRUCTURES

Abstract:

A touch panel includes an array of touch electrode cells, each touch electrode cell including portions of a plurality of touch electrodes, such as portions of intersecting row and column touch electrodes that include a patterned conductive material. In some examples, the area of patterned conductive material per unit area can be different for different touch electrode cells of the touch panel. For example, the touch panel can include touch electrode cells with increased pattern densities at locations where the overall area of the touch electrode cell may be less than the overall area of other touch electrode cells in the touch panel, such as at corners, notches, perforations, and/or edges of the touch panel.
